I am an engineer before I am a specialization.

I am Arnab. I have always been the person who wants to know how something works, why it stopped working, and whether I can make it better.

That habit is not limited to software. I repair my own things, look for practical workarounds, and build tools when the right one does not exist. I enjoy the moment when a confusing system becomes understandable enough to improve.

Professionally, I work as a Principal Engineer on complex products. My role reaches beyond frontend implementation: I connect product intent, architecture, workflows, APIs, standards, verification, and the way teams deliver.

Right now I am especially interested in AI-first delivery: shortening the loop from an idea to a rapid prototype, evaluating it, learning from real user behavior, and using that evidence to improve the next version.

Outside day-to-day product work, I build browser-native experiments that make systems easier to understand: small computers, audio tools, simulations, and interactive demonstrations.
